I doubt I’ll have time to comment much on this, though I hope to follow the thread.
But I do want to register a vote along (probably) with Auggy on this one.
I find it to be another of the (scripturally quite common) both/and situations. Saint Paul, as James noted, is the main exponent of sanctification in the NT, and even in scripture as a whole (the prophets sort of talk about it sometimes, but not to the same degree.) And while I think the instant/immediate sanctification proponents have a good case, such as in the verses James noted, I think the progressing sanctification proponents have a good case, too–also primarily from Saint Paul!
Theologians (usually Calv, but also some Arms) who distinguish hard between “justification” and “sanctification”, recognize the both/and, and tend to put “sanctification” as the process and “justification” as the immediate result. But a year or two ago I did a (private) word-study on both terms in the NT, and I found that they just don’t split out that way so cleanly, whether in Paul’s usage or (on much rarer occasions) elsewhere. I finally decided Paul was just going back and forth between terms for compositional variety’s sake; maybe in the case of one epistle (I forget which, I’ve slept since then and I don’t recall where I put my notes) it was a sign of two epistles having been archived together for posterity, but Paul was using each term in both now-and-developing-later senses.
I’m not married to the both/and position though (not in this case ). If someone was able to convince me the usage could be resolved one way instead of the other, I wouldn’t mind either way.
PS, and following up in some agreement with Bob: if it was only crucified, I could think of that in terms of my sin still being in the process of crucifixion, still hanging on the cross. Maybe that’s Paul’s grammar, too (present-tense continuing?), but I seem to recall (perhaps wrongly–I’m not where I can check at the moment) that it’s supposed to be crucified and buried. Which seems rather more final. (And maybe already risen again with Christ in the new creation!)
That could be some evidence that, as the joke goes, I’m doing it wrong. (Though in any case it isn’t supposed to be me doing it anyway but Christ in me, whether immediate, progressing, or both.)
